Olmos optioned to make room for Eovaldi
By Tyler Emerick / MLB.com
PHOENIX -- To make room on the roster for Nathan Eovaldi, the Marlins optioned left-handed reliever Edgar Olmos to Double-A Jacksonville following the club's 3-2 victory over the D-backs on Monday night.
In his first Major League stint, Olmos made five appearances, tossing five innings and allowing nine runs (four earned) on seven hits. He also struck out a pair and walked three.
The 23-year-old's best outing came in his big league debut when he threw 1 1/3 scoreless innings against the Phillies in Philadelphia.
Eovaldi will make his season debut Tuesday when he takes the mound to start the second game of the Marlins' three-game set with the D-backs at Chase Field.
Slowey moving to long relief with Eovaldi's return
PHOENIX -- With Nathan Eovaldi set to enter the Marlins' rotation and make his season debut Tuesday, Marlins manager Mike Redmond announced Monday that Kevin Slowey will move to the bullpen and serve as the club's long-reliever.
"I just think Slowey has pitched in that role before and he's better equipped to handle it," Redmond said. "So that'll be how it goes now for a while. It doesn't mean it's going to stay like that."
Of Slowey's 14 appearances this season, 13 of them have been starts. The right-hander has struggled of late, allowing at least four earned runs in five of his last seven outings.
"I talked to him, he's fine," Redmond said. "He's a professional. I was very honest with him and told him exactly what we needed. He's on board to do whatever we need him to do. He understands the situation."
Tom Koehler (0-5, 5.09 ERA) was another candidate to be replaced in the starting rotation, but the Marlins decided to keep the rookie in place.
"I think it's good experience for him," Redmond said. "It's good for him to stay in the rotation and get in as many innings as possible."
Morrison returns to lineup, batting fifth
PHOENIX -- After missing the last four games due to back tightness, Logan Morrison returned to the lineup Monday against the D-backs, batting fifth and manning first base for the Marlins.
Morrison, who missed the first two months of the year rehabbing from offseason knee surgery, hadn't played since last Tuesday against the Brewers.
"He's feeling good," Marlins manager Mike Redmond said. "He says he's ready to go, so hopefully we can keep him out there this time."
Morrison was first activated off the 60-day disabled list on June 9 and went 4-for-9 with six total bases in his first three games before tweaking his back.
"Stuff happens when you don't play for as long as I didn't," Morrison said. "I couldn't ignore it, so I got it addressed. But yesterday it felt better than the day before and today it feels better than yesterday."
No surgery needed for Coghlan
PHOENIX -- Chris Coghlan saw a spine specialist on Monday in Dallas and the doctor confirmed that the 27-year-old won't need surgery on his injured back. Instead, the Marlins outfielder, who was placed on the 15-day disabled list on June 9, will treat the injury with rest.
"He's just going to take time," Marlins manager Mike Redmond said. "He'll take it easy and then resume baseball activities. I don't know how long that'll be, I don't have a time frame, it just depends on how he feels."
Even though the Marlins still don't know how much time Coghlan will miss, Redmond was relieved the injury isn't as bad as it could have been.
"You just never know," Redmond said. "Now, it's just a matter of it calming down. He says he feels good, though, I talked to him."
Coghlan had been hot at the plate before getting hurt, batting .343 (23-for-67) with four runs and nine RBIs in 73 plate appearances since May 18.
Stanton dominant in NL West stadiums
PHOENIX -- Giancarlo Stanton isn't sure why, but whenever the Marlins' outfielder plays in National League West parks, his bat seems to have even more pop to it than normal.
That trend was in full effect Monday at Chase Field as the 23-year-old hit two homers and drove in all three runs for Miami in the club's 3-2 victory over the D-backs.
Counting Monday's bounty, Stanton now has hit 25 home runs in 48 career games in NL West stadiums.
"I don't know, if I knew what it was, I'd bring it with me to every park," Stanton said.
Stanton, who grew up in California, thought maybe proximity to home has something to do with the staggering power numbers, which also include 20 doubles and 50 RBIs.
"More family gets to watch me play out here, that's all I can attest it to," said Stanton, whose father was in attendance Monday.
• On the disabled list with right shoulder inflammation, Henderson Alvarez will make his second rehab start on Tuesday for Class A Jupiter and could rejoin the Marlins after just two more outings. The right-hander will throw up to 70 pitches.
• Marlins manager Mike Redmond sees a direct correlation between Juan Pierre's 12-game hitting streak and the club's improved offensive output of late.
"It's been huge, he still has great speed and he has the ability to change an inning with it," Redmond said. "We don't have a lot of those guys and he's done a nice job these last couple weeks being that catalyst."
