Monuments of the BLB

Nine decades of BLB history are in the books, 1980s through 2060s. Rather than argue the GOAT question across all of history at once, the cleanest way to settle it is to break it down decade by decade, using the leaderboards for that ten-year window (min. 3,000 PA for hitters, min. 1,000 IP for pitchers), and then see who stands above the rest in each one.

One honest caveat before diving in: this method has a blind spot. A player whose prime ran from the middle of one decade to the middle of the next gets his numbers split down the center, half showing up in one ten-year bucket and half in the other. A genuine Hall of Famer could easily post numbers strong enough to be the best player of a full decade if you measured his actual prime, but come up short in both halves once the calendar cuts him in two. Nobody on this list got left off for that reason, but it’s worth remembering that the names here are the best of each fixed window, not necessarily the best of each generation.

.445 OBP, .519 SLG, .964 OPS, 973 RBI, 74.16 WAR

Gremades led the 1980s in on-base percentage (.445), OPS (.964), wOBA, and weighted runs created, and his 74.16 WAR led the decade outright by a wide margin over Keppel’s 61.48. He also topped the league in runs scored (1,005) and walks (1,196), an old-school combination of contact, patience, and scoring runs that doesn’t show up as raw power but adds up to the most valuable hitter of his decade. His .328 batting average tied for the league lead too, meaning he got on base at an elite clip without sacrificing average for walks the way pure on-base specialists usually do.

Rest of the Top Five: Keppel, Woodbury, Campoveroe, Lumar

160 wins, 2.74 ERA, 2,417 K, 79.01 WAR

Theodore led the 1980s in strikeouts (2,417) and WAR, the highest pitching WAR of the decade by a real margin over Guardamagni’s 76.48. He backed it up with top-two finishes in wins, innings pitched (2,301.1), and quality starts (233), the profile of a true workhorse ace who took the ball every fifth day for a full ten years and rarely had a bad one. His 1.083 WHIP ranked inside the decade’s top ten as well, proof the strikeout totals came without sacrificing control.

Rest of the Top Five: Guardamagni, Corrigan, Mapalo, Parongao

.538 SLG, .925 OPS, 351 HR, 1,131 RBI, 92.62 WAR

Knight’s calling card was pure power: he led the 1990s outright in home runs (351) and isolated power (.267), and posted a 92.62 WAR, one of the highest hitting totals in this whole exercise. Add a .538 slugging percentage, a .925 OPS, and 1,131 RBI, and it’s as complete a power-hitting résumé as this exercise has produced. He also ranked second in the decade in games played, meaning all that thump came from an everyday player, not a part-timer padding rate stats.

Rest of the Top Five: Maeda, Woodbury, Haynes, Guzman

122 wins, 2.39 ERA, 2.70 FIP, 52.77 WAR

Dimmick’s case rests on pure stuff: his 2.391 ERA and 2.696 FIP both ranked second in the decade, trailing only a banned contemporary. He backed that with a 61.47 rWAR, the second-best mark of the era, and a stingy 1.068 WHIP that ranked among the decade’s best. Miles actually posted a fractionally higher WAR that same decade (53.15 to 52.77), but Dimmick’s superior ERA and FIP make him the better pick for the decade’s best clean résumé, and unlike a lot of command specialists, he didn’t sacrifice bulk to get there, logging 175 quality starts along the way.

Rest of the Top Five: Miles, Morgan, Suárez, Tucker

.411 OBP, .534 SLG, .945 OPS, 281 HR, 834 RBI, 69.19 WAR

Fujii led the 2000s in the rate categories that separate the great from the merely good: OPS (.945), wOBA (.412), and isolated power (.243) all belonged to him, on top of the decade’s best weighted runs created total (1,100.48). He also led the league outright in runs scored (999) and tied for the home run crown (281), proof the rate-stat dominance came with real thump behind it. His 69.19 WAR led the league outright, though not by much. Cardenas was breathing down his neck the entire decade with a 68.92 WAR of his own, one of the closest decade races in this exercise. Fujii’s rate-stat sweep is what tips it in his favor.

Rest of the Top Five: Cardenas, Alvarez, Gaston, Trujillo

142 wins, 2.70 ERA, 2,468 K, 57.51 WAR

Herberholz didn’t just lead the 2000s in WAR, he led it in practically everything: wins (142), strikeouts (2,468), innings pitched (2,092.2), starts (324), quality starts (219), rWAR (59.92), and strikeout rate (28.64%). Mejia actually had the better command numbers that decade, leading ERA, FIP, and WHIP outright, but Herberholz’s sheer bulk of dominance across the workload categories put him clearly on top. Leading eight different pitching categories, WAR, wins, strikeouts, innings, starts, quality starts, rWAR, and strikeout rate, in the same ten-year window is not something anyone else in this exercise managed to do.

Rest of the Top Five: Mejia, Hernandez, Schuh, Neal

.323 AVG, .411 OBP, .539 SLG, 262 HR, 953 RBI, 80.62 WAR

McPherson’s decade WAR ranks among the highest of any single decade in this sample, trailing only Knight’s 92.62 and Morla’s 82.32. He led the league outright in hits (1,933), runs scored (1,047), plate appearances, games played, and BABIP (.385), the kind of full leaderboard sweep that shows up maybe once or twice in a league’s entire history. His .411 on-base percentage also topped the decade, and his 1,281.66 weighted runs created total is itself the highest of any hitter in this exercise. No hitter in this exercise put together a more complete decade.

Rest of the Top Five: Davila, Murillo, Piekarski, Lona

165 wins, 2.54 ERA, 2,426 K, 63.89 WAR

Yahn led the league in innings pitched, strikeouts, starts, and ERA, and posted a 78.62 rWAR, the highest single-decade rWAR of any pitcher in this sample. His decade WAR trails only Theodore and Carroll in this exercise, still a clear step above everyone else.

Rest of the Top Five: Evans, Lippert, Taylor, Reeves

.350 AVG, .406 OBP, .565 SLG, 296 HR, 1,002 RBI, 82.32 WAR

Morla led the league in batting average, on-base percentage, OPS, wOBA, and weighted runs created in the same ten-year window, then backed it up with more hits and more runs scored than anyone else in the decade. His decade WAR trails only Knight’s 92.62 in this sample, and comfortably clears McPherson’s 80.62 for second, and the full offensive package, average, patience, power, and pure production, is as complete as it gets.

Rest of the Top Five: Yonke, Lewis, Owens, O’Hearn

154 wins, 2.33 ERA, 2,274 K, 75.93 WAR

There isn’t a meaningful pitching leaderboard from the 2020s that Carroll isn’t at or near the top of. ERA (2.327), FIP (2.300), wins (154), strikeouts (2,274), quality starts (243), WHIP (0.884), K%-BB% (24.32%), he led all of them outright. His 0.884 WHIP is stingy enough that opposing lineups were basically better off not stepping in against him at all. His WAR trails only Theodore’s 79.01 for the highest of any pitcher in this sample, and his 71.72 rWAR is right there among the era’s best too. It’s about as complete a decade as a pitcher can turn in.

Rest of the Top Five: Teel, Engstrom, Stone, McDade

.587 SLG, .954 OPS, 461 HR, 1,192 RBI, 65.88 WAR

Hutchinson didn’t lead his decade in batting average or OPS, that distinction belonged to Rice and Jessee at the top of the rate-stat boards, but he led in the categories that measure total value delivered over ten years. Most home runs (461). Most RBI (1,192). The best WPA in the league (41.55), and the highest weighted runs created total in the decade (1,186.33) to go with it. This is a hitter who did his damage in bulk rather than in gaudy averages, and by decade’s end nobody had produced more of it.

Rest of the Top Five: Swope, Quezada, Morris, James

3.01 ERA, 2.57 FIP, 2,108 K, 57.34 WAR

Plumley’s decade was built on swing-and-miss stuff. He led all 2030s pitchers in strikeouts (2,108), strikeout rate (30.54%), and K%-BB% (24.11%), and topped the decade in WAR. His FIP (2.574) and WHIP (1.056) both ranked second in the league too, evidence the strikeout totals came without sacrificing much in the way of results. Worth noting: Arballo actually out-worked everybody in the decade, leading the league in wins (171), innings pitched (2,360, the heaviest workload of any pitcher in this entire sample), and rWAR (62.90). Different kind of ace, same decade, and a real argument for the runner-up spot.

Rest of the Top Five: Schick, Arballo, Reutter, Jong

.369 OBP, .529 SLG, .898 OPS, 314 HR, 929 RBI, 67.14 WAR

Hullinger’s game was balance. He wasn’t the peak-season monster that Graham was that same decade (Graham edged him in WPA, 36.13 to 35.10), but he ranked top ten across on-base percentage (.369), wOBA, total hits (1,641), and stolen bases (433), a rare combination of patience, power, and speed that added up to the best all-around value in the league. Few hitters in this exercise show up in that many different categories at once, which is exactly why his 67.14 WAR led the decade without a single runaway number to point to.

Rest of the Top Five: Capps, Graham, Robertson, Neal

131 wins, 2.34 ERA, 2,226 K, 61.62 WAR

Vines paired the era’s best raw stuff with genuine run prevention, the rare pitcher who led his decade in both strikeout rate (34.34%) and ERA at the same time. He backed it with the second-best rWAR of the decade (58.99) and finished second in strikeouts (2,226), trailing only Gomez. His WAR is the fourth-highest of any decade-leading pitcher in this sample, behind only Theodore, Carroll, and Yahn, and the strikeout-rate-and-ERA double is a rarer combination than his raw win total lets on.

Rest of the Top Five: Bell, Gomez, Encinia, Foley

.317 AVG, .370 OBP, 898 Runs, 1,729 Hits, 56.55 WAR

There’s no single monster category that defines Ludin’s decade, and that’s the point. He led the league in runs scored (898) and stayed near the top of the hits, doubles (tied for second at 405), triples (third at 111), and stolen base (fourth at 673) leaderboards all at once. His WPA (28.59) ranked second in the decade too, further evidence the value wasn’t just compiled counting stats. It’s a profile built entirely on doing a little bit of everything well, and nobody produced more total value from that kind of game over the 2050s.

Rest of the Top Five: Jennings, Rabah, Irwin, Lee

145 wins, 3.06 ERA, 2,678 K, 55.38 WAR

Peter’s case rests on total value and volume. He led the decade in rWAR (55.32), strikeouts (2,678), and quality starts (214), while finishing second in both wins (145) and FIP (2.993). He wasn’t just a compiler either, his 27.05% K%-BB% ranked inside the decade’s top six, evidence the volume came with real swing-and-miss stuff behind it. That combination of bulk and dominance made him the clear ace of his decade.

Rest of the Top Five: Spence, Rothstein, Blume, Tamarovsky

.313 AVG, .578 SLG, .927 OPS, 863 RBI, 32.55 WPA, 59.35 WAR

Van Hook’s case comes down to leading the two numbers that matter most in a single decade: WAR (59.35) and WPA (32.55). He backed both of those up with the batting title (.313) and top-five finishes in slugging (.578), OPS (.927), and RBI (863). His wOBA (.381) ranked fourth in the decade as well, one more sign the average and the power numbers were both real rather than one propping up the other. It’s the most complete hitting résumé of the most recently completed decade, no real weakness anywhere in the profile.

Rest of the Top Five: Burch, Wolfson, Booth, Castro

135 wins, 2,126.2 IP, 2,027 K, 52.30 WAR

Mount anchored the most recently completed decade with the heaviest workload in the league (2,126.2 innings) and runner-up finishes in wins (135) and quality starts (192), plus a top-four strikeout total (2,027). Spence deserves real mention here too: he led the decade outright in wins (136), strikeouts (2,282), and quality starts (201). Mount gets the decade on WAR, the single best measure of total value, but Spence’s fingerprints are all over the era, and either name would be a defensible answer for the era’s best arm.

Rest of the Top Five: Dillard, Spence, Cochell, Good
