News
	Riley O'Brien struck out three batters while allowing two walks in a scoreless outing to earn the save in Wednesday's 1-0 win over the Angels. Chase Davis Thu, Jul 23rd	Arizona's bullpen heading into Opening Day consists entirely of right-handed pitchers, and Ginkel and Juan Morillo have been tasked with handling tough left-handed hitters. Ginkel's career splits are nearly identical against both sides (.312 OBP vs. righties, .311 vs. lefties), though in 2025 he was more effective against lefties, posting a 90 OPS+ against them compared to 137 OPS+ when facing right-handed hitters. Bruno Mulé Tue, Mar 24th
