Dodgers notes: Chin-hui Tsao, Sergio Santos, Kyle Jensen

LOS ANGELES -- The main purpose of Wednesday afternoon's press conference at Dodger Stadium was the introduction of new shortstop Jimmy Rollins, but there were a few other tidbits of information relevant to the Dodgers.

Relief pitcher Chin-hui Tsao hasn't yet officially signed a minor league pact with the Dodgers, but when he does it likely won't include a non-roster invitation to big league camp in spring training, which makes sense for someone who hasn't pitched professionally since 2009.

The reason for that layoff was a ban from the Chinese Professional Baseball League for fixing games, which is enough to give pause at the very least, or at least cause great concern. But the Dodgers, as well as the other teams interested in Tsao, went through the proper channels before courting the right-hander.

"We consulted Major League Baseball on it, and we were cleared to pursue him," Dodgers general manager Farhan Zaidi said on Wednesday. "There were several teams involved."

The evidence against Tsao was sketchy, it seems, and Tsao, the first Taiwanese pitcher in major league history, was likely used as an example to discourage future game-fixing, a problem that plagued the CPBL for years. The CPBL stepped in in December, successfully pressuring the Australian Baseball League to disallow his signing in that league. But no such attempt has been made with Tsao set to rejoin a major league organization.

"We've had communication with them about their investigation just like we've communicated to Major League Baseball about theirs," Zaidi said.

★★★

Kyle Jensen was acquired from the Marlins on Nov. 17 but has since been designated for assignment and sent outright to Triple-A Oklahoma City, removing him from the 40-man roster. Zaidi said Jensen would be in big league camp at spring training as a non-roster invitee.

★★★

The Dodgers on Thursday confirmed the signing of relief pitcher Sergio Santos, who pitched for the Blue Jays in 2014. Santos was signed to a minor league deal with an invitation to big league camp at Camelback Ranch.

The full list of known non-roster invitees to date is here, and can be found on the front page of the site, or at truebluela.com/nri.

★★★

The Dodgers will hold its player development mini-camp in Los Angeles next week, the eighth annual gathering of several prospects with instruction both on and off the field, learning the ins and outs of major league life. However, this year's program is a little more truncated than in previous years, packing in everything into roughly three days. The full list of players participating haven't yet been announced.

★★★

As of Wednesday night, Zaidi said the Dodgers weren't any closer to a deal involving Erisbel Arruebarrena. If the Dodgers don't trade the shortstop, who was designated for assignment on Dec. 31, they can send him outright to Triple-A Oklahoma City, provided he clears waivers.

"We've got a couple more days for that process to play out," Zaidi said. "It's hard to say."

We will find out a resolution on Arruebarrena's status one way or another by the weekend.
