Former Jay Roberto Osuna gets win in return from suspension

Roberto Osuna needed five pitches for a clean inning and a nice on-field impression on his new teammates.

Osuna earned the win in his first appearance with Houston after Marwin Gonzalez hit a three-run homer with two outs in the ninth inning, lifting the Astros over the San Francisco Giants 3-1 on Monday night.

Osuna (1-0) hadn't pitch in the majors since May 6 while serving a 75-game suspension for violating MLB's domestic violence policy. The former Blue Jays closer was arrested and charged with assaulting his girlfriend May 8 in Toronto. Few details have been made public, and the next court date in the case is scheduled for Sept. 5.

"Especially like being in such a great team with great teammates, it's easy to forget about the stuff that's going on off the field, and being able to play and help the team win is unbelievable," Osuna said. "I really like my teammates. They've been treating me with a lot of respect, and I'm really comfortable."

Osuna was acquired from Toronto last Monday in a deal that sent back closer Ken Giles, and he became eligible to pitch Sunday . A few fans booed when he entered the game in the eighth inning, and Osuna calmly retired the side in order.

"It was a quick look obviously with five pitches," manager A.J. Hinch said. "He's got a good arm. First game back is always important, it's the next step for him to get incorporated into our games, coming away with the win. A good first impression on the field."

Hector Rondon closed out the 2-hour, 26-minute game with his 12th save in 15 chances.

San Francisco closer Will Smith (1-2) blew his second save in nine opportunities after issuing walks to Alex Bregman and Yuli Gurriel. Gonzalez followed with a towering drive to left for his 10th homer.

Brandon Crawford hit a solo homer in the sixth inning, but San Francisco failed to do enough to back rookie Dereck Rodriguez's latest gem.

The two starters had a nice duel but nothing to show for it.

Rodriguez struck out seven with no walks and allowed three hits in seven innings. Charlie Morton, a 12-game winner, struck out eight over seven innings with three walks and three hits.

The Giants lost for just the third time on days Rodriguez starts — and this marked just his 11th in the big leagues. The son of Hall of Famer Ivan Rodriguez has quickly emerged as one of the top rookies in the National League.

Rodriguez has allowed three or fewer runs in 10 of his starts.

"I take it in after every start. I enjoy it, I think about it a lot of the time but when I'm out there it's just me, Buster (Posey) and the hitter, whoever's hitting, so I think that's what's helped me get to the point where I'm at, my concentration when I'm in the game," Rodriguez said. "It's awesome being in the situation I'm in."

Ballpark fire

A concession stand caught fire approximately three hours before first pitch near section 121 on the main concourse of AT&T Park. The blaze was out by the time the fire department arrived, there were no expected delays and no fans had been let inside yet, according to Jorge Costa, Giants senior vice-president of ballpark operations.

"This happens occasionally," he said.
