10/17 Tampa Bay vs Cleveland

Tampa Bay starting pitcher: Nick Martinez Cleveland starting pitcher: Tanner Bibee

This is Game 4 of the AL Championship Series, a best-of-seven. Tampa Bay has 1 win and Cleveland has 2 entering the game. Tampa Bay finished 98-64 and Cleveland 85-77. Tampa Bay won the regular-season series 6-3, but Cleveland took Game 3 by 3-2.

Martinez is 15-6 with a 3.14 ERA, but his 3.94 FIP and 81.1% strand rate suggest the results ran better than the underlying numbers. His SwStr% is 8.2% and CSW% is 25.4%. Over his last five starts (23.2 IP), his FIP is 3.70 with a 14.7% K-BB%, though SwStr% (8.1%) and CSW% (23.6%) are flat to slightly lower. His average fastball speed rose from 92.4 on Sept. 11 to 93.2 on Oct. 8. Against Cleveland this season he has thrown 13 innings over two starts with no runs, 9 strikeouts and 1 walk. That came with a .194 BABIP and a 100% strand rate, so it is a very small sample.

Bibee is 7-15 with a 4.44 ERA and 4.55 FIP, so his results match his process. His SwStr% is 10.2% and CSW% 26.9%. Over his last five starts (22.0 IP), he allowed 18 runs with a 1.59 WHIP, but a .361 BABIP and 56.6% strand rate mean the results were worse than his 4.29 FIP. His home FIP is 5.10. His velocity climbed from a 93.2 average on Sept. 9 to 96 on Oct. 9, but that outing lasted 0.1 innings. Against Tampa Bay he has pitched 11 innings over two starts with a 3.27 ERA and 2.47 FIP, losing both.

Neither lineup is confirmed, so this uses each team's previous lineup. Tampa Bay has a 112.3 wRC+ on the season, but only .201/.231/.227 wOBA and one homer over its last five games. Yandy Diaz is 3-for-7 against Bibee and Chandler Simpson 3-for-5. Cleveland's wRC+ is 100.6, with five homers and a .241/.310/.303 line in the last five games. Jose Ramirez is hitting .450 over that stretch, but he is 1-for-6 against Martinez.

In the bullpens, Tampa Bay has used 10 innings across 7 pitchers recently, Cleveland 12 innings across 8. Over the last 10 games, bullpen ERA is 3.96 for Tampa Bay and 2.49 for Cleveland. It is 10.1°C at Progressive Field, with a 45% chance of rain.

In summary, Martinez's ERA looks better than his FIP, while Bibee's recent results were worse than his process. Whether Tampa Bay's cold bats recover and Cleveland's hot hitters can handle Martinez is the key. Bullpen use after the starters could also decide the game.
