Rangers' No. 4 prospect Joey Gallo's introduction to Double-A ended with a bang Monday. The reigning Minor League home run king hit a walk-off three-run homer and Frisco defeated Midland, 7-4.

Gallo was promoted from Class A Advanced Myrtle Beach over the weekend and was making his debut with Frisco on Monday. His first game in a RoughRiders uniforrm began inconspicuously and he was hitless going into the ninth inning. But with two out and two on, Gallo drove a 2-0 pitch out to left-center field and deep into the Texas night for his first Double-A home run and victory.

Gallo, ranked No. 78 on MLBPipeline.com's Top 100 Prospects list, went 1-for-5 with four RBIs and three strikeouts Monday. His home run was his 22nd of the year, moving him back into a tie with Cubs' No. 2 prospect Kris Bryant atop the Minor League leaderboard. Bryant had taken the lead earlier in the night with a homer of his own for Double-A Tennessee.

Gallo hit .323/.463/.735 with 21 home runs in 57 games with Myrtle Beach. He led the Carolina League in home runs, on-base percentage, slugging percentage, runs (53), RBIs (50) and walks (51).

Right-hander Luke Jackson, the Rangers' No. 7 prospect, started the game for Frisco, though he was long gone by the time Gallo hit his home run. Jackson allowed four runs on three hits and two walks in 5 1/3 innings. He also struck out nine batters and now leads the Texas League with 74 strikeouts in 72 1/3 innings this season.

Moreland still mulling options with ankle surgery

CLE@TEX: Washington talks about Moreland's injury

ARLINGTON -- Just one day after it was announced that he would have ankle reconstructive surgery and be sidelined for three months, Mitch Moreland has decided to at least explore a different option for his left ankle.

Moreland is considering foregoing the reconstructive surgery and having his os trigonum bone removed instead. Rangers catcher Geovany Soto had the same bone removed earlier this season in February.

The benefit of choosing the os trigonum procedure over the ankle reconstruction surgery is that if it is successful, Moreland could be back in three to four weeks, as opposed to three months. He's been battling ankle pain nearly all season, and said Monday that as hard as he tried to fight through it until the end of the season, he no longer could.

He's seeking a second opinion before he decides which procedure he'll choose.

"I just know he wanted a second opinion," Rangers manager Ron Washington said. "I haven't heard when they're going to do it, but I would imagine it'd be as soon as possible."

Odor feeling OK, listed day to day with shoulder sprain

CLE@TEX: Odor gets hurt sliding back on pickoff

ARLINGTON -- Rangers second baseman Rougned Odor exited Sunday's game against the Indians in the fifth inning with a sprained right shoulder, and he is listed as day to day.

Though he was not in the lineup for the Rangers on Monday night against the Indians, Odor said he feels fine and is ready to play. He had a shoulder injury about three years ago as well.

"It was no big issue last time, so there's no issue now," Odor said. "I'm ready. There's no problem."

Rangers manager Ron Washington said it was nice to hear some good news in the midst of all the injuries the Rangers have had to deal with.

"He can hit, but we're going to keep him from throwing for a day or so," Washington said. "He's available to come off the bench if I need him in an emergency, so it was good news."

Holland making measured progress with knee injury

Rangers Most Likely: Derek Holland, Round 1

ARLINGTON -- Despite earnestly hoping he'd be bound for a medical rehab Monday after taking another pitcher's fielding practice, Rangers pitcher Derek Holland learned that he's not quite ready yet, and he will likely head to Arizona on Wednesday to do a couple of live batting practice sessions while the Rangers are on the road.

Holland fell at home in January, injuring his left knee, and had surgery for it.

He spent between 10 and 15 minutes on the field Monday fielding bunts both towards first and third, as well as directly at him. He also practiced covering first base.

"I'll do a couple of live BPs on the road trip while they're gone, come back and we'll see how everything goes from there," Holland said. "I feel good. I feel like there's still room for improvement, and we'll go from there."

Though he knows that ultimately the Rangers are looking out for his safety by not allowing him to begin a rehab assignment yet, the look on his face Monday showed his evident frustration.

"I feel like I can go out and play with it," Holland said. "But the real thing is that's not going to happen."

Rangers manager Ron Washington said Holland is certainly looking healthier but that it is still clear he's not ready. He'll be re-evaluated June 24 after the Rangers complete a nine-game road trip.

In 2013, Holland was 10-9 with 33 starts and a 3.42 ERA. He had 189 strikeouts in 213 innings.

"Yeah, it's better, but it's not ready for competition. Our projection was after the All-Star break, so no need to be getting excited right now," Washington said. "It's better, he's able to move around, but it's not ready for competition. … My eyes tell me he's not ready."

Also working out on the field before the Rangers' matchup with the Indians Monday was Engel Beltre, who has been on the disabled list with a fractured tibia in his right leg. Beltre sustained the injury in winter ball, when he was hit by a pitch.

Beltre will head to Arizona along with second baseman Jurickson Profar, who tore a muscle in his right shoulder in March.

"[Beltre] ran the bases, he's running well," Washington said. "Next step for him I guess would be to go down to Arizona and get some action, do some sliding and all of that."

Worth noting

The Rangers have agreed to terms with second-round pick Ti'Quan Forbes from Columbia (Miss.) High School for $1.2 million and fourth-rounder Brett Martin from Walter State Community College in Tennessee on a $475,000 deal. They have also signed sixth-rounder Jose Trevino.
