Abreu has insisted the Derby did not affect his swing, saying he's been pulling and jumping to the ball.
"I need to stay back and let the ball travel more," Abreu said.
Despite batting .224 in July, Abreu has reached base in 21 of the team's 23 games entering Friday. He has drawn 16 walks over that span, tied for fifth-best in the National League, and owns a respectable .340 on-base percentage for the month. Abreu went 1-for-5 Thursday with a strikeout.
Abreu has played in 103 of the team's 104 games, and received his first day off last week. Manuel said Abreu needed a mental break, and that he believes his slugger is close to regaining his time and rhythm.
The 41 home runs, a record in the Derby, were 10 more than Abreu's single-season best, which he set in 2001. He crushed a record 24 home runs in the first round of the Derby.
An All-Star in each of the past two seasons, Abreu is two home runs shy from becoming the third player in Major League history with seven straight 20 homer/20 stolen base seasons. The other two are Barry and Bobby Bonds.
Both Jimmy Rollins and Kenny Lofton were in the lineup Friday, but dealing with minor pains.
Rollins tweaked his right ankle running out an infield single Monday, and Lofton has been dealing with lingering hamstring issues. Manuel said Rollins told him the ankle was all right.
Friday marked Lofton's 49th game since returning from the disabled list, after straining his right hamstring. However, Lofton left the game with acute inflammation of the left patella, and is considered day-to-day.
Rollins leads the team with 24 stolen bases, while Lofton is third best with 11 swipes. Rollins was picked off first base in Thursday's series opener by Colorado catcher Danny Ardoin.
Lofton went 1-for-3 Thursday with a walk, two runs and two RBIs. He knocked a two-out single up the middle in the fifth to put the Phillies ahead. Rollins went 2-for-4 with a walk and two runs.
Reliever Terry Adams, who started the season with the Phillies, cleaned out his locker and told Triple-A Scranton/Wilkes-Barre manager Gene Lemont he was retiring immediately for personal reasons on Thursday.
Adams allowed three runs in the eighth inning, and was the losing pitcher. Lamont told reporters he did not plan on Adams coming back.
In 16 games with the Phillies, Adams went 0-2 with a 12.63 ERA before being designated for assignment. He went 1-2 with a 4.41 ERA in 14 appearances for Scranton.
Adams, who has been in the Majors since 1995, also spent the 2002-03 seasons with the Phillies.
The Phillies send Cory Lidle (8-9, 4.63 ERA) to the mound Saturday. The right-hander, who is in the midst of a three-game losing streak, is 0-1 against the Rockies this season. Colorado starts Aaron Cook, who will be making his first appearance since last Aug. 7, when he suffered blood clots in both his lungs.
