(SportsNetwork.com) - Arizona righty Chase Anderson started his career by winning his first five starts. He's dropped four in a row since.

Anderson will try to get off the schneid on Monday when the Diamondbacks open a three-game series with the Miami Marlins at Chase Field.

The 26-year-old hurler's struggles continued on Wednesday in Pittsburgh, as Anderson surrendered three runs and eight hits with three walks in just 3 2/3 innings, dropping him to 5-4 on the year to go along with a 3.91 ERA.

Anderson has pitched to a 5.03 ERA over the course of his slide.

"I've been working in the bullpens and doing pretty good in between (starts) but I've got to carry it into games," Anderson said after the loss to the Bucs. "You don't last in this game very long if you don't go deep in the game as a starting pitcher. I've got to get better for sure."

Arizona salvaged the finale of its set with the red-hot Atlanta Braves on Sunday, as Paul Goldschmidt's two-run homer propelled the Diamondbacks to a 3-1 victory.

"I wasn't sure. I knew it probably had the distance, but it started fair and kept going," Goldschmidt said on his home run. "I saw it hit the pole and come down. I was pretty happy."

Nick Evans had an RBI double and Martin Prado scored for the Diamondbacks, who finished 4-5 on a nine-game road trip.

Starter Wade Miley (4-6) surrendered just one run on five hits and a walk with eight strikeouts across 6 2/3 strong innings to earn his first win since May 10 against the White Sox.

Miami, meanwhile, has won four of five after a series win in St. Louis over the weekend. On Sunday, Jarrod Saltalamacchia hit a three-run homer and Henderson Alvarez tossed seven solid innings as the Marlins took an 8-4 win.

Alvarez (6-3) conceded just one run on five hits with three strikeouts for the Marlins, who have won a franchise-record 10 straight starts with the right- hander on the mound.

"He's really stepped up and taken over that ace role for us," said McGehee about Alvarez. "He pretty much did today what he has done all year for us."

Getting the call for the Marlins on Monday will be righty Tom Koehler, who is 6-6 with a 3.48 ERA. Koehler was terrific on Wednesday versus Philadelphia, as he scattered three hits over six scoreless innings. He also struck out seven and walked one.

"I've said it all year and even last year, this guy, I thought, was our most improved pitcher from last year to this year," Redmond said.

Koehler, who lost his only other start to the D-backs, was placed on the paternity list after the game and welcomed his first child to the world the next day when his wife gave birth to a girl.

Arizona has taken 12 of 17 from the Marlins.
