Tampa Bay Rays vs Athletics Starting Lineup — Tuesday, Aug 11, 2026

Tampa Bay Rays at Athletics (2026-08-11). Nick Martinez vs Mason Barnett at Sutter Health Park.

Starters — Nick Martinez has a 2.65 ERA and 1.10 WHIP across 129 innings, with 5.09 K/9, 1.4 BB/9, and 1.05 HR/9. His profile is built on command and contact management more than swing-and-miss. Over his last three starts, he has allowed 6 earned runs in 17.2 innings, including two scoreless outings and no walks in any of those three appearances, which supports the current upward trend. Mason Barnett has a 5.56 ERA and 1.38 WHIP in 34 innings, with 9.53 K/9, 4.5 BB/9, and 2.12 HR/9. The strikeout rate is strong, but the walk rate and home run rate have been damaging. In his last three starts, he has allowed 10 earned runs in 12.2 innings, and the recent form points downward despite 15 strikeouts in that span.

Teams — Tampa Bay enters with a .732 OPS, 529 runs scored, a 3.70 team ERA, and a 1.15 team WHIP. The Rays have also gone 8-2 over their last 10 games, which adds to the case that they are bringing both steadier run prevention and better recent form into this matchup. The Athletics have a .715 OPS and 516 runs scored, so the offensive gap is not massive on the surface, but their pitching staff has been a major issue with a 5.45 team ERA and 1.50 team WHIP. They are also 2-8 in their last 10 games, which reinforces the contrast in current team performance. Tampa Bay looks more stable on the mound and cleaner in run prevention, while the Athletics rely more on Barnett’s strikeout ability to offset traffic and damage.
