Arizona at San Diego 9:40 ET
Diamondbacks over Padres- The Tuesday night pitching matchup features Arizona right-hander Zac Gallen (4-2, 2.91 ERA) and San Diego left-hander Sean Manaea (3-3, 3.95). The game also could mark the return of Padres manager Bob Melvin, who has been in the COVID-19 protocol since between games of a June 11 doubleheader. Gallen, 26, will be looking for his first win since May 30 as he makes his 13th start of the season. In 65 innings, Gallen has given up 23 runs (21 earned) on only 48 hits and 16 walks with 60 strikeouts. He has a 0.985 WHIP and a .201 opponents' batting average. Gallen has six quality starts. He has allowed two or fewer runs in 10 of his 12 games, including one or none in six. Against the Padres, he is 1-2 with a 3.38 ERA in five career outings, 0-0 with a 3.12 ERA in two starts in San Diego. Manaea hasn't faced the Diamondbacks since holding them hitless over seven innings in the second game of the season on April 8 in Phoenix. The only blemish was a walk before he departed after striking out seven in an 88-pitch outing. The Padres are only 6-6 in Manaea's 12 games, although he has nine quality starts. Arizona had won three of its past four games before dropping the series opener. Take ARIZONA!
