Manager Eric Wedge said Rodriguez's hand was improving after being gashed in three places by the spikes of a sliding Danny Valencia of the Twins and would possibly be available if needed Saturday in reserve.
But Liddi, starting at third base against the Rangers in Saturday's game, remains the first option as the back up at shortstop.
"I haven't told him that yet, but yeah," Wedge said with a laugh.
The 6-foot-4, 220-pound Italian played 24 games at short for Triple-A Tacoma earlier this year.
As for Seager, Wedge is still getting a feel for how the 23-year-old can handle the position at the Major League level. Saturday was his sixth start at short after playing most of the season at second base in the Minors and third with Seattle.
He impressed the skipper with his adjustment on Friday. After failing to handle a hard-hit backhand deep in the hole by Nelson Cruz in the fourth, he made an excellent play on a similar one-hop scorcher by Adrian Beltre leading off the eighth.
"The first one, he kind of comes off a little quick with his eyes and misses it; the second one, he looks it in and makes a nice play," said Wedge. "It's a great example of two similar plays, oddly enough in the same game, to where he gets better.
"And I think he's been a little more comfortable on his turns. We turned a couple [of] nice double plays yesterday. We're getting a feel for his range and instincts. He's holding his own right now and I'd like to see more of him."
Wedge reiterated Saturday that outfielder Casper Wells is "pretty much done for the season" with more tests scheduled early next week as doctors try to pinpoint an equilibrium problem. It's the same story with shortstop Brendan Ryan and the disk problem in his neck.
"Weighing everything with Ryan, risk-reward, I think that's a long shot," said Wedge.
