Phillies' Thomson laments worst start since 2015: 'We're not used to this'

The Philadelphia Phillies aren't accustomed to losing and are feeling the effects of their worst start since 2015.

"We're not used to this," manager Rob Thomson said after Sunday's 4-2 loss to the Atlanta Braves. "We're not."

The Phillies have lost five straight and are 8-13 - their worst start through 21 games since 2015, when they finished with 99 losses. Sunday's defeat also marked their 10th in 13 contests. They also went 2-7 on the homestand, making it their worst showing in 17 years.

Despite carrying the fourth-highest payroll in baseball, the Phillies rank 27th in runs scored and own MLB's worst run differential. No one is doing much to generate offense outside of Kyle Schwarber and Bryce Harper, and the pitching staff's 4.84 combined ERA is one of the highest in the majors.

Despite the team's struggles, Thomson is confident his club will get out of its funk.

"A lot of frustration," Thomson said. "We're disappointed. We're frustrated. I know they're trying hard. Sometimes, they're trying too hard. I think guys are upset. We're off to a slow start here, but it's going to get better."

Philadelphia starts a seven-game road trip Monday with four games against the Cubs in Chicago.
