His last three starts have been sharp: 5.2 innings, 0 earned runs, 6 strikeouts, 1 walk; 5 innings, 2 earned runs, 3 strikeouts, 1 walk; and 5 innings, 1 earned run, 3 strikeouts, 2 walks. The recent trend is down on ERA, but the season profile still shows traffic on the bases and notable home run risk. Williams has a 3.71 ERA, 1.07 WHIP, and 133.1 innings, backed by 11.34 K/9, 2.57 BB/9, and 1.42 HR/9. His last three starts were 7 innings, 2 earned runs, 12 strikeouts, 1 walk; 7 innings, 0 earned runs, 11 strikeouts, 0 walks; and 6 innings, 5 earned runs, 11 strikeouts, 0 walks. The trend is also down, and his recent form stands out for swing-and-miss dominance plus strong control.

Teams — Arizona brings a .709 OPS and 508 runs with a .243 team average, while its pitching staff owns a 4.20 ERA and 1.30 WHIP. The Diamondbacks are 7-3 over their last 10, which supports the idea that the offense is in a better current rhythm than Cleveland’s. The Guardians have a .680 OPS, 441 runs, and a .231 team average, with a 3.79 team ERA and 1.27 WHIP. Cleveland’s overall run prevention has been better than Arizona’s, but the lineup has been lighter by both OPS and total runs, and the club is 2-8 in its last 10. From a betting angle, this sets up as Arizona carrying the stronger recent team form and better offensive production, while Cleveland counters with the more reliable season-long pitching indicators and the stronger starter on paper.
