Slumping Ryan Howard was not in the Phillies’ starting lineup against a left-handed pitcher for the second time in six post-all-star break games on Wednesday night, and his future with the team is in serious question.

Manager Ryne Sandberg would not use the word “platoon,” but that’s exactly what his actions suggest.

“As far as the lineup, that will be a day-to-day thing,” Sandberg said before the game.

The manager made it clear he would not let Howard’s huge contract dictate playing time.

“It's about wins and losses out here,” Sandberg said. “When the game starts, it's about winning the game and being productive and chipping in and doing the part and doing something to help win a game. If that means playing somebody else there and there's production right away -- that's trying to win a baseball game.”

Darin Ruf, recalled from Triple A on Tuesday, started at first base for the Phillies against Giants’ lefty Madison Bumgarner. Clearly, the team was prepping him to get some time at first as he played four of his last five games at Triple A at that position.

“I’m interested to see what he can do,” Sandberg said of Ruf. “I know what [Howard] can do. I've seen him for 100 games. I know what he can do. I think it's important to see what a guy like Darin Ruf can do also going forward.”

Over the first 100 games of the season, Howard, 34, has hit .224 with 15 homers, 57 RBIs and 118 strikeouts in 371 at-bats. Howard’s OPS, a dreadful .682, ranks 126th out of 162 qualifying major-league hitters. His OPS ranks 21st out of 23 qualifying major-league first basemen.

Over his last 25 games, Howard is hitting just .168 (16 for 95) with a .269 on-base percentage and a .221 slugging percentage. He has just three extra-base hits in that span, two doubles and a home run that came with the Phils ahead, 7-1, late in a game at Milwaukee.

Sandberg was careful not to disparage Howard, but he sounded very much like a man who was shopping for a first baseman. Prospect Maikel Franco could get a look later in the season.

Sandberg denied that he was looking for Howard’s replacement.

“But I think it's also important to see and gauge other players to see where they're at,” he said.

Howard is signed for at least two more years. Why would Sandberg want to gauge other players if Howard’s future with the team wasn’t in serious question?

Phillies officials have spent a lot of time discussing ways to retool their disappointing team in recent weeks. Trades are on the way and there could be several before next week’s non-waiver trade deadline.
