When it comes to knowing how roster upheaval effects team results, the evidence shows that Salt Lake manager Keith Johnson's opinion is on the money.

Want proof?

Other than Los Angeles Angels pitcher Jerome Williams joining the Bees on a rehab assignment, Salt Lake has not had a roster change since June 23. Since that date, the Bees, who open a four-game home series with Tacoma on Wednesday, have won six of nine.

Prior to that, Salt Lake had lost nine of 10.

"There will probably be [a roster change] tomorrow," said Johnson with a laugh he probably wasn't really feeling. "I've always said, when the big club is healthy we're stronger."

Williams is expected to make his second rehab start Friday before rejoining the Angels. The right-hander was placed on the disabled list June 19 after experiencing shortness of breath following a start June 18 against the San Francisco Giants. In 13 games with the Angels, Williams is 6-5 with a 4.46 ERA and 56 strikeouts.

In 2011, Williams appeared in 11 games for the Bees in 2011 and went 7-2 before joining Los Angeles. His presence should help Salt Lake's inconsistent pitching.

Salt Lake started winning when its starters began going deeper into games. In the last homestand, after losing 12-4 to Pacific North leader Reno, the Bees won the next three while the Aces scored a total of nine runs in the losses.

"It helps when starters pitch deeper into games," Johnson said. "The bullpen has been throwing up zeros." ———
