Castellanos went 1-for-4 with two RBI in Monday's win over the Cubs.
Castellanos delivered a key two-RBI single in the fifth inning to give the Padres a lead they wouldn't relinquish. It was a much-needed hit for the veteran, who hadn't recorded a hit since April 12 and has seen his playing time dwindle. Across 55 plate appearances in 2026, Castellanos is slashing .154/.200/.212 with three doubles, seven RBI and one run scored.
