Team Picks data is live at the time of writing and is subject to change.

SP Griffin Jax (3.41 xFIP) will take the ball for Tampa Bay after appearing in relief against the Yankees in the ALDS. The right-hander struck out 4 over 2.0 innings in that outing, his first appearance since September 26.

Jax was fantastic for the Rays in the regular season, posting a 3.53 ERA, 116 strikeouts, and a 1.18 WHIP over 112.1 innings. The biggest question for him remains how long his leash will be. Jax threw just 52 pitches in his last regular-season outing, followed by one 32-pitch outing in the ALDS.

Williams (2.85 xFIP) gets the start for Cleveland after delivering one of the postseason's most impressive performances in Game 5 against the White Sox. Williams struck out 12 batters over 6.0 innings, carried a no-hitter into the sixth, and helped the Guardians secure the series-clinching win.

The right-hander has been one of baseball's most dominant pitchers this season, notching 248 strikeouts over 184.1 innings with a 3.76 ERA and a 1.11 WHIP.

Cleveland's offense will need to continue doing its part against a Tampa Bay team that finished the regular season with the sixth-best wRC+ (104) compared to the Guardians' 97 (22nd). 

3B José Ramírez remains the key to unlocking this lineup, and he's delivered in the postseason. After finishing the regular season with a 92 wRC+, his career low, he's come to life in October with a hit in five straight games and multiple hits in three of them.

Here are the key stats and trends behind our Rays vs. Guardians prediction on the winner for Thursday's ALCS Game 3.

Unless otherwise noted, data used in this article is from FanGraphs, Baseball Savant, and MLB.com.

• I give the Guardians the edge in all three major facets (offensive, starting pitching, relief pitching) today.
• Offensively, the Guardians have been the better team thus far in October. Cleveland owns a 96 wRC+ in the playoffs, second-best behind only the Milwaukee Brewers (107).
• The Guardians rank well ahead of the Rays, who have struggled at the plate in the postseason, posting just a 68 wRC+ (eighth out of 12 teams).
• Cleveland also holds a sizeable starting-pitching edge. Williams has an xFIP over half a run better than Jax's, and he's been even better at home by posting a 2.63 xFIP at Progressive Field compared to 3.15 on the road.
• The Big Rig has been lights out in day games to the tune of a 2.84 ERA in day games this season vs. 5.05 in night games.
• Jax, meanwhile, has the complete opposite day/night splits. In day games, opposing batters hit .265 against him, compared to .224 in night games.
• The bullpen matchup is as even as it gets, with both teams ranking first and second in postseason xFIP.

Rays vs. Guardians Picks, Player Stats for NLCS Game 3 on PrizePicks: 10/15/26

Here are two Rays vs. Guardians player picks to consider on PrizePicks for Thursday's ALCS Game 3. Today's MLB picks include Griffin Jax and Gavin Williams.

Rays P Griffin Jax vs. Guardians: 4 Strikeouts

• Jax hasn't thrown over 52 pitches in almost a month. If any of the top three hitters in the Guardians' lineup have a strong at-bat against him the first time around, this could easily be a situation where the Rays ask Jax to just get through the order once.
• Cleveland struck out 20.8% of the time during the regular season, the fifth-lowest rate in baseball.
• That high-contact approach has carried into the postseason, with the Guardians owning the second-lowest strikeout rate among postseason teams (21%).
• Jax also has some of the most pronounced home/road splits in all of baseball. At home, he owns a 11.55 K/9 and a 2.82 xFIP vs. marks of 6.71 and 4.08, respectively, away from home.

Guardians P Gavin Williams vs. Rays: 6.5 Strikeouts

• The Rays finished the regular season with an MLB-low 18.8% strikeout rate and have continued to put the ball in play at a high rate throughout the postseason. Their playoff K-rate of 17.5 is the best among all teams.
• Tampa’s projected lineup has seven (yes, seven!) players with a strikeout rate sub-20.2%, and three have a K% sub-14.0%.
• While Williams is the clear ace of this staff, it is still the postseason, and managers tend to have quicker hooks for all their pitchers in crucial must-win games.
• The Guardians' bullpen has the best xFIP (2.72) in the postseason, so manager Stephen Vogt may not have an issue turning to them if Williams starts to wear down in the middle innings.

Add Gavin Williams + Guardians to cover the spread to your PrizePicks lineup now.
