Suarez has been Cincinnati's starting third baseman the past two years after switching from shortstop. He .260 last season and set career highs with 26 homers and 82 RBIs on a team that finished last in the NL Central at 68-94.
Arbitrators Mark Burstein, Jeanne Wood and James Darby are expected to issue a decision Tuesday, a day after hearing arguments.
Players are 5-2 in cases decided thus far and 16 players, in addition to Suarez, remain scheduled for hearings through Feb. 16. Twenty-four would be the most hearings since 1990.
Springer asked for a raise from $4,075,000 to $10.5 million and was offered $8.5 million. His case was bolstered when Mookie Betts defeated the Boston Red Sox in the first hearing last week and was awarded $10.5 million rather than the team's $7.5 million offer.
Springer tied the World Series record with five home runs, connecting in each of the final four games, as Houston won its first title. Springer batted .379 (11 for 29) with five walks in the seven games against the Los Angeles Dodgers. He set career bests during the season with a .283 average, 34 home runs and 85 RBIs.
