SAN DIEGO -- Padres third baseman Manny Machado will appeal the one-game suspension he received for his actions during his ejection on Saturday night in Colorado.

Major League Baseball announced the suspension and a fine for Machado on Monday, "for aggressively arguing and making contact with umpire Bill Welke." That's a notion Machado disputes.

"I didn't think I touched him," said Machado, who was in the lineup for Monday's series opener against Milwaukee because of the appeal. "The video says it all. We're going to appeal it, and we think we've got a good case."

Machado's camp seems hopeful he'll come away with merely a fine from the incident. But in truth, the video isn't all that conclusive.

After a borderline 2-2 fastball from Rockies right-hander German Marquez in the top of the fifth inning Saturday night, Machado turned to argue with Welke, the home-plate ump.

Welke ejected Machado promptly. Then, Machado went off, a tirade that included a thrown bat and more choice words from the top step of the dugout.

But the incident in question occurred at the beginning of the argument between the two, when Machado first realized he'd been tossed. The Padres third baseman turned toward Welke, threw his helmet and began yelling. It's unclear if contact was made, but Welke pointed to his right arm immediately.

"He pointed, but I was way too into the zone of letting him hear what I had to say on what I thought about the call," Machado said. "I didn't think I touched him."

There's no timeline for when Machado's appeal will be heard, but if he wins it, his suspension could be negated. His fine will not be. If he loses the case, Machado will have to serve his suspension immediately.

Machado is slashing .261/.343/.448 with 13 homers and 39 RBIs in the first season of the 10-year, $300 million deal he signed with the Padres in the offseason.

"We have our case," Machado said. "We'll just wait to see what the appeal comes back with."

Mejia recalled

The Padres promoted catcher Francisco Mejía from Triple-A El Paso on Sunday, optioning fellow rookie backstop Austin Allen in a corresponding move.

Mejia broke camp with the big league club this season, but he struggled out of the gate, posting a .167/.207/.259 slash line before he was sidelined with a knee injury.

Earlier this month, Mejia was activated from the injured list, but he was optioned to Triple-A El Paso to find his swing. Sure seems like he found it. In 18 games there, he was hitting .365/.411/.746 with four homers.

As things stand, Austin Hedges is still the team's starter behind the dish, but Mejia seemingly has a chance to earn a more regular role. Hedges is unquestionably one of the sport's best defenders, but he's been one of the league's worst hitters this year, too.

"Franky didn't grab hold of anything last time,” Green said. “He'll have an opportunity to grab hold of playing time. Things change as the season plays out."

Worth noting

• The Padres transferred outfielder Franchy Cordero to the 60-day disabled list Monday, a clerical move so they could select the contract of Kazuhisa Makita. Makita arrived Monday to provide cover for a beleaguered bullpen.

The move is retroactive to early April, when Cordero was originally placed on the injured list with a right elbow sprain. Now, he's battling a left quad injury, which he sustained during the rehab stint. There's no timetable for Cordero's return, but the early prognosis doesn't seem good.

"He's not close to returning at this point," Green said.

• Lefty reliever Jose Castillo is being evaluated for left forearm tightness that he sustained during a rehab outing with El Paso on Saturday. Castillo hasn't pitched this season after he sustained a left forearm strain in Spring Training. He was approaching a return and could've been activated this week, if not for the setback.

"Hopefully we don't have to reboot the whole thing," Green said. "Hopefully in a couple days, he can just resume and carry on where he was."

• The Padres optioned left-hander Nick Margevicius to Double-A Amarillo, clearing space for Makita's activation. Margevicius was hit hard Sunday in Colorado, where he became the first pitcher in Padres history to allow nine earned runs without making it through the second inning. The 22-year-old rookie started the season strong, but his ERA has basically doubled since the end of April. It now sits at 6.41.
