SAN DIEGO — Andy Green’s first ejection as a big league skipper gave Mark McGwire his first chance to manage.

Wil Myers and Derek Norris hit two-run homers and Adam Rosales added a solo shot for the San Diego Padres, who rallied to beat the Pittsburgh Pirates 5-4 Tuesday night.

Green was tossed for arguing after a sequence in which Andrew McCutchen was awarded home on a balk by Colin Rea, and then the umpires twice reversed their call, eventually giving the Pirates the run. McGwire came out to lead Green off the field.

“As long as I’ve been around I don’t think I’ve seen a reverse of a reversal. I think that’s where the frustration was on my part,” Green said.

McCutchen was on third base with Francisco Cervelli batting with two outs in the third. McCutchen broke for home while Rea (1-1) was in his windup. Rea was called for a balk when he took his right foot off the rubber, and McCutchen scored. The four umpires huddled and reversed their call and McCutchen was sent back to third. After Pirates manager Clint Hurdle came out to argue, the umps huddled again and once again awarded McCutchen home, giving the Pirates a 2-0 lead.

Green came out to argue and was tossed. He threw down his cap and pointed at each of the umpires before McGwire led him off the field.

“I was genuinely outraged at the chain of events that occurred, as they occurred,” Green said.

Green said Hurdle should have been ejected for arguing a balk, but crew chief Brian Gorman said Hurdle was OK in doing so.

With the Padres trailing 3-0, Myers hit a two-run homer to left with two outs in the fourth, his third. Norris gave the Padres a 4-3 lead with his two-run shot to straightaway center with one out in the fifth, his first. Both were off Francisco Liriano (1-1).

After Norris’ homer, Arquimedes Caminero came on and allowed Rosales’ homer that bounced off the top of the facade of the Western Metal Supply Co. brick warehouse in the left field corner. It was his first.

“They took some good swings. Clearly when Mark McGwire is managing, they hit home runs,” Green quipped.

David Freese and Liriano hit RBI singles for the Pirates.

Rea allowed three runs and seven hits in five innings, struck out six and walked one. Fernando Rodney pitched a perfect ninth for his second save.

Liriano allowed four runs and six hits in 4 1/3 innings.
