SAN DIEGO-To the surprise of many, Wednesday’s 4 p.m. Major League Baseball trade deadline passed without the Orioles making any deals.

Players such as reliever Mychal Givens and infielder Jonathan Villar could have been complementary pieces to contenders, but the deadline passed without any movement.

There had been speculation that there might be interest in the Orioles’ best player, Trey Mancini, but he’s staying put, too. The same for infielders Hanser Alberto and Renato Nunez and starting pitcher Dylan Bundy.

The Orioles dealt their most marketable player, right-handed starter Andrew Cashner, to the Boston Red Sox on July 13, which essentially kicked off the trading season.

In previous years, teams could make trades after July 31, but players had to pass through waivers first. The deadline for those trades was August 31, but that’s been eliminated.

Once November comes, the Orioles can consider other deals. Minor league deals and waiver pickups can continue, so it’s likely that the Orioles aren’t through making additions and alterations to their roster.

Changes will have to be made for Thursday’s home game against the Toronto Blue Jays. The Orioles went with 14 pitchers for Tuesday’s game in San Diego after outfielder Dwight Smith Jr. was placed on the 10-day injured list with a strained left calf muscle.

Pitcher Chandler Shepherd, who was in San Diego as a possible substitution for another pitcher, was added to the active roster for the game, but wasn’t used. He was optioned to Norfolk after the trading deadline.

Infielder Jose Rondon, who was acquired on waivers from the Chicago White Sox, is supposed to be in Baltimore on Thursday. He could replace Shepherd on the roster, or the Orioles could try to designate him for assignment and send him to Triple-A Norfolk since he’s out of options.

If the Orioles want to add an outfielder to replace Smith, they can summon DJ Stewart, another left-handed hitter, from Triple-A Norfolk.

The Orioles have already used 50 players this season, six short of last year’s club record of 56.

NOTE: In a minor league deal, the Orioles traded right-handed  pitcher Dan Straily to the Philadelphia Phillies for cash considerations. Straily was 2-4 with a 9.82 ERA in 14 games with the Orioles and had been outrighted to Triple-A Norfolk, where he was 4-0 with a 2.38 ERA in six starts. He’ll report to the Phillies’ Triple-A club in Lehigh Valley.
